We were pleased with the outcome of our settlement, and with the efforts put forth by Judge Bronstein.  It was a marathon session, but Judge Bronstein worked with both clients and urged us to be patient until there was sufficient movement towards settlement.  Thanks to Judge Bronstein and ADR Systems.
